Abstract	Pectin is a polysaccharide mainly used in food processing industries as an emulsifier, thickener, stabilizer and in pharmaceuticals as an excipient, wall material and bio adhesive for improving delivery and efficiency. Raising demand for pectin, pushes to explore unconventional plant-based sources for the extraction of pectin. This work is aimed to explore the possibility of extracting pectin from the peel of banana varieties and to decipher the chemical and techno-functional properties. Among the varieties, Nendran, a plantain banana recorded higher pectin recovery (23.42 %), swelling power (23.10 gg(-1)), anhydrouronic acid (AUA) content (72.86 %) and emulsifying activity (46.19 %). Pectin from the banana peels exhibited the equivalent weight (g/mol) ranging from 943.40 (var. Bhimkol) to 1282.05 (var. Nendran). Morphological observations revealed that the extracted pectin has fragments with uneven sizes and inter-particle voids in the structure. Banana pectin behaved similar to commercial pectin in terms of rheological, textural and structural profiles. HPLC analysis and NMR spectra confirmed the dominance of galacturonic acid in the banana peel pectins. The study unveiled and opened up the avenues of utilizing banana peel as a complementary biomass for the extraction of pectin which could be used in different industrial applications.
